for the components of the binary. Note that in their original work [1]} derived this relation under the assumption of equal mass components.
This value is too high to be reconciled with the luminosity of the protostellar core (\(100\hbox{\hspace{1.99997pt}$L_\odot $}\) ) and the core masses derived from the dust thermal emission at arcsec scale by [2]}. Applying Eq. REF  to protostar B, which lies at a distance of \(1.2\)  (\(\sim 9000\)  au) from A and assuming the same orbital period the mass required would be even larger than \(\sim 20M_\odot \) .
